Article Synopsis
  • The Hawthorne effect describes how clinicians alter their behavior when they know they are being observed, a phenomenon that has not been extensively studied in trauma care in low- and middle-income countries (LMICs).
  • In a study conducted in Ghana, trained observers monitored emergency units to see if their presence would improve performance in achieving key performance indicators (KPIs) in trauma care, which was initially hypothesized to happen.
  • Results showed that while clinician performance was higher immediately after observers arrived, it dropped significantly over 14 months, matching the hypothesis of the study and providing valuable insights for future trauma and surgical research in LMICs.

Background: Road safety authorities in high-income countries use geospatial motor vehicle collision data for planning hazard reduction and intervention targeting. However, low-income and middle-income countries (LMICs) rarely conduct such geospatial analyses due to a lack of data. Since 1991, Ghana has maintained a database of all collisions and is uniquely positioned to lead data-informed road injury prevention and control initiatives.
